IMPROVEMENT IN SPlNDLE-STEPS FOR SPINNING-FRAMES.

Specification forming part of Letters Patent No. 184,742, dated November28, 1876; application filed February 16, 1 876.

invented certain new and useful Improve-- ments relating toSpindle-Steps for Cotton- Spinning Frames, of which the following is aspecification 1 The intense velocities impressed on spindles, and thenecessity for plentiful lubrication, have induced various refinements inthe steps or provisions for supporting and steadying the foot of eachspindle. Among them has become in a degree standard the plan ofinserting into the substantial rail a vertical cylinder of cast-iron,containing a lining or bushing of brass, with some provisions forreceiving oil at the top.

Our improved step belongs to this class. We enlarge the cast-ironcylinder above the rail, and provide thereby a capacious receptacle foroil; provide a removable cover for the exclusion of dirt; construct theparts so that, on elevating the cover, the oil in the receptacle isplainly exposed to view, and arrest any whirling motion of the oil whichmight be received from the spindle, by providing fixed stops close tothe spindle, which allow a sufficiently free access of oil, but preventany whirling motion being imparted to the mass. We prefer to constructthese stops by extending the bushing upward to, or a little above, thehighest proper level of the oil, and provide limited spaces for theaccess of the oil to the spindle, by sawing across the bushing at itsupper end.

However the stops to prevent a whirling motion of the oil may bearranged, We extend upward the bushing in the solid or undividedcondition a little above the. top of the cast-iron cylinderor, in otherwords, a little above the bottom of the oil-vessel. This prevents thevery bottom portions of the oil from finding access to the-spindle, andforms a space in which any dregs or heavy particles in the oil maysettle and accumulate. An

occasional wiping out of the bottom of the oil-vessel and refilling ofthe receptacle with clear oil insure the efficient lubrication, andprevent any access of grit to the spindle for an indefinite period.

The accompanying drawings form a part of this specification, andrepresent what we consider the best means of carrying out the invention.

Figure 1 is a side elevation of the spindle with the other parts insection, and Fig. 2 a horizontal section.

Similar letters of reference indicate like parts in both the figures.

G is a stationary rail. A is a cylinder of iron, held firmly in a holein the rail G by means of a pinching-screw. M is the oil-receptacle,formed by an annular enlargement, A and a cylindrical rim or circularwall, A, both formed in the same casting with the cylinder A. B is abrass bushing, fitted in the part A, and extending up a considerabledistance in the oil-vessel M, as represented. Its upper part is dividedby a saw-kerf, b. The parts of the bushing thus divided, and whichproject upward in close proximity to the spindle D, we will denominateB. They serve asa stop to prevent the mass of oil outside from receivinga whirling motion from the rotation of the spindle. O is a movablecover, surrounding the spindle and matching over the exterior of theoil-vessel.

The coverO may be lifted by the thumb and finger of the attendant, andthe interior of'the oil-vessel is thus fully exposed to view. Inspectiondetermines instantly whether or not there is a liberal supply of oilremaining in the vessel, and on introducing more oil the eye observeseasily the rate at which it bev comes filled.

The advantages of having a liberal supply of oil around the spindle havebeen long appreciated. Ordinarily, the whirling motion imparted theretois liable to throw out the oil unless there is an internal flange on topof the interior of such vessels, however high the stops B, with thespindle D and vessel M, as cover is lifted; and when, the nose of anoiler specified.
